7 6 Serial port check digit
The serial port mode of the communication side can
be different.
0 0 8N1 (default).
0 1 8O1
1 0 8E1
1 1 8N1 (equivalent 00).
5 4 3 TTL serial port baud rate (bps).
The baud rate of the two sides of the communication
can be different;
The serial port baud rate has nothing to do with
wireless parameters and does not affect the wireless
transceiver characteristics.
0 0 0 The serial port baud rate is 1200
0 0 1 The serial port baud rate is 2400
0 1 0 The serial port baud rate is 4800
0 1 1 The serial port baud rate is 9600
(default).
1 0 0 The serial port baud rate is 19200
1 0 1 The serial port baud rate is 38400
1 1 0 The serial port baud rate is 57600
1 1 1 The serial port baud rate is 115200
2 1 0 Wireless air rate (bps).
The lower the air speed, the farther the distance, the
stronger the anti-interference performance, and the
longer the transmission time;
Both communicating parties must have the same
over-the-air wireless transmission rate.
0 0 0 The air speed is 2.5k (default).
0 0 1 The air rate is 5k
0 1 0 The air rate is 12k
0 1 1 The air rate is 28k
1 0 0 The air rate is 64k
1 0 1 The air speed is 168k
1 1 0 The air speed is 168k
1 1 1 The air speed is 168k
